The vacuum between the two glasses prevents heat conduction and keeps the temperature for a longer time.
It is manufactured by vacuuming a single piece of glass, hence it has extra durability. Despite its durable structure, it is very lightweight.
It is beautiful and easy to clean, yet tough and durable. Made from hand-blown borosilicate glass, lighter and thinner than other glasses.
Not recommended to be washed in the dishwasher. Because the heat conduction between the two glasses can be disrupted and the glass's feature may be lost.
